GEORGE LEWIS, OF PANAMA, NEW YORK, ASSIGNOR TO HIMSELF, RALPH HOYT, AND C. W. HOYT, OF SAME PLACE.

CHURN'POWER- Specification forming part of Letters Patent No. 43,076, dated June 7, 1864.

To all whom it may concern.-

Be it known that I, GEORGE Lnwrs, of Panama, in the county of Chautauqua and State of New York, have invented a new and Improved Churn-Power; and I do hereby de clare that the following is a full, clear, and exact description thereof, which will enable any person skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a sectional side elevation of my invention. Fig. 2 is a front elevation of the same.

Similar letters of reference in both views indicate corresponding pal ts.

The object of this invention is to produce a churn-power by which the dasher receives areciprocating motion in the churn, and at the same time an oscillating motion is imparted to the churn itself, so that by this compound motion the process of churning is considerably facilitated.

The nature of my invention and its peculiar advantages will be readily understood from the following description.

A represents a frame, made of wood or any other suitable material and in any suitable form or shape. This frame is provided near its top with a cross-bar, B, which form the fulcrum for two oscillating arms, (J, the lower ends of which are connected by a cross-bar, D. The cross-barD forms the fulcrum for two arms, E, the lower ends of which are connected by the cross-bar F, and this cross-bar is pro vided in its middle with a journal, which fits into a suitable box in the upper end of the dasher-staff G.

H is the churn-barrel, which is supported by a cross or platform, I, connected to the lower ends of the swinging bars J, which have their fulcra on pins b, inserted in brackshown in Fig. l of the drawings.

and pivots d, which are rigidly inserted in the inner surfaces of the swinging bars J, project into slots 6 in the oscillating arms 0. A handle, K, projecting from the cross-bar D, which connects the oscillating arms 0, serves to impart motion to the entire mechanism.

By pushing the handle in the direction of the arrow marked on it in Fig. 1 the arms 0 and E assume an angular position, and by the combined action of the slots e on the pivots d and of the ends of the cross-bar F on the slots in the swingbars J and the churn H are thrown in an angular position, as clearly At the same time the dasher-staff G, being connected to the cross-bar F, is drawn up, and by reversing the motion of the handle the motion of the churn and that of the dasher are reversed. By the combined action of the reciprocating dasher and oscillating churn-barrel. the g1ob ules of the milk are completely broken, and the butter separated in a short time; and, furthermore, by the momentum of the churn and its contents, the resistance of the dasher is partially overcome, and the operation of the whole mechanism is rendered easy. I

This device can be made very cheap. It requires no complicated machinery, no gearwheels or metal fastenings, everything being so arranged that it can be riggedv up by any carpenter. It is applicable to ordinary barrelchurns, and it facilitates the labor of churning, to a great extent.

What- I claim as new, and desire to secure by Letters Patent, is-

The oscillating bars J, eith slots to and pivots d, in combination with the hinged arms 0 E, cross-bars, D F, dasher-staff G, and tub or barrel H, all constructed and operating in the manner and for the purpose substantiallyas herein shown and described.
